Objective To explore the diameter change of the extrahepatic bile duct before and after laparoscopic cholecystectomy (LC). Methods From Jan. 2006 to Dec. 2007， 113 patients including chronic gallstone cholecystitis （n=55）, inactive cholecystolithiasis （n=46） and gallbladder polyps （n=12） were collected and treated by LC. The diameters of their extrahepatic bile ducts were measured by B ultrasonography before operation， 3 months and 6 months after operation. These data were collected and analyzed retrospectively. Results The diameters of the extrahepatic bile ducts of all patients before LC， 3 months and 6 months after LC were (5±2) mm, (8±2) mm and (6±2) mm respectively. And in chronic gallstone cholecystitis patients they were (5±2) mm, (9±2) mm and (6±2) mm respectively， in inactive gallstone cholelithiasis patients they were (5±2) mm, (8±2) mm and (6±2) mm respectively， and in gallbladder polyps ones they were (5±2) mm, (7±2) mm and (5±2) mm respectively. Conclusion The change of the extrahepatic bile duct diameter after LC is a dynamic process. It is enlarged on the third month after operation than before operation. In the sixth month after operation marked retraction occurs, and compared with before operation, it shows no obvious statistic significance.
Objective To summarize the treatment experience for concomitant diseases of other abdominal organs in laparoscopic cholecystectomy （LC）. Methods The clinical data of 176 patients with LC and concomitant diseases of other abdominal organs were analyzed retrospectively， including preoperatively diagnosed cases （such as 53 with liver cyst， 15 with choledocholithiasis， 7 with chronic appendicitis， 5 with inguinal hernia， 4 with renal cyst， and 6 with ovarian cyst） and intraoperatively diagnosed cases （such as 72 with abdominal cavity adhesion， 4 with internal fistula between gallbladder and digestive tract， 3 with Mirizzi syndrome， and 7 with unsuspected gallbladder carcinoma）. Results All the operation were successfully completed in 176 patients without severe complications， including 53 cases treated with LC plus fenestration of hepatic cyst， 15 with choledocholithotomy， 7 with appendectomy， 5 with tension free hernia repair， 4 with renal cyst fenestration， 6 with oophorocystectomy， 72 with adhesiolysis， 3 with fistula resection plus intestine neoplasty， 2 with intraoperative cholangiography plus choledocholithotomy， 5 with LC plus gallbladder bed complete burning， and 4 cases treated with conversion to open surgery （1 with intestinal fistula repair， 1 with choledocholithotomy， and 2 with radical resection for gallbladder carcinoma）. Conclusions It is safe and effective to treat gallbladder diseases complicated with other concomitant diseases simultaneously with laparoscopic operation， if the principles of surgical operation are followed and the indications and applicable conditions are strictly followed. And conversion to open surgery is necessary.
Objective To explore the prevention and treatment of injury to brangches of the middle hepatic vein in laparoecopic cholecystectomy. Methods The clinical data of 27 hemorrhage cases of injury to brangches of the middle hepatic vein in laparoscopic cholecystectomy from January 2008 to January 2010 were analyzed retrospectively. Results All 27 hemorrhage cases were successfully stopped bleeding under laparoscopy by the way of packing hemostasis （n=17）, clamping hemostasis （n=6）, and suturing hemostasis （n=4）. In the 3 hemostasis methods, the operating time and amout of bleeding in the cases with packing hemostasis was the shortest and the least, respectively, which was （90.26±12.46） min and （240.32±80.15）ml, respectively, but the differences of the 3 methods were not statistical significance （P＞0.05）. Conclusions During laparoscopic cholecystectomy, gallbladder bed should be seperated in the correct plane to avoid injury to brangches of the middle hepatic vein. The most important to ensure surgery safety is applying the right surgical hemostasis method to stop bleeding quickly, and the open surgery will be the first choice in the right time when the difficult hemostasis occurs under laparoscopy.
ObjectiveTo summary the standard treatment for early gastric cancer. MethodsThe current early gastric cancer treatment guidelines around the world were analyzed and the standardized treatment patterns for early gastric cancer were concluded. ResultsThe accurate preoperative evaluation for early gastric cancer is the basis of standardized treatment which can be divided into staging evaluation and histological evaluation.The staging evaluation is focused on the gastric wall invasion and lymph node involvement of the tumor while the histologic evaluation emphasize the histological type and grading of the tumor.According to the precise evaluation for early gastric cancer, endoscopic surgery, laparoscopic surgery, open surgery, and multimodal therapy can be applied individually to the patients.Different treatment methods have their indications, but the indications of the therapies in different guidelines are suggested with slight differences. ConclusionIn clinical practice, the choice of treatment should be made with comprehensive consideration of diagnosis and individual characteristics of patients to achieve the most benefit on prognosis.
Objective To systematically review the efficacy and safety of laparoscopic hepatectomy (LH) and open hepatectomy (OH) for patients with hepatocellular carcinoma (HCC). Methods PubMed, EMbase, The Cochrane Library, CBM, WanFang Data, CNKI databases were electronically searched to collect the case-control studies about LH vs. OH for patients with HCC from inception to December, 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software. Results A total of 28 studies involving 1 908 patients were included. The results of meta-analysis showed that: the LH group was superior to OH group on complications (OR=0.35, 95%CI 0.26 to 0.48, P<0.000 01), hospital stay (MD=–4.18, 95%CI (–5.08, –3.29),P<0.000 01), and five years overall survival rate (OR=1.65, 95%CI 1.23 to 2.19,P=0.000 7) and disease-free survival rate (OR=1.51, 95%CI 1.12 to 2.03, P=0.006). However, no significant differences were found in one year and three years overall survival rate, disease-free survival rate, and postoperative recurrence rate. Conclusion Current evidence shows that the LH is superior to OH for the treatment of HCC, and may be amenable to surgery because of its safety and longtime efficacy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
ObjectiveTo study the significance, methods, and technique of group No.6 lymphadenectomy of the laparoscopic gastrectomy with D2 lymph node dissection for distal gastric cancer. MethodsThe relevant data of the 141 examples of group No.6 lymphadenectomy of the laparoscopic gastrectomy with D2 lymph node dissection for distal gastric cancer from Jan.1, 2008 to Dec.31, 2011 were retrospectively analysized. ResultsOne hundred and forty-one patients were successfully completed the group No.6 lymphadenectomy of laparoscopic distal gastrectomy with D2 lymph node dissection. With the number of cases of operation increasing, the operation time, bleeding volume, incidence rate of complication, and the number of operation transit cases stepped down year by year, and the number of the lymph node dissection stepped up (P < 0.000 1). No case died of the lymphadenectomy of the group No.6 lymph node. The medium vessels of colon, pancreas, and the gastroduodenal artery were the anatomic landmarks of the group No.6 lymphadenectomy. The space between the anterior lobe and the posterior lobe of transverse mesocolon and the prepancreatic space were the important surgical plane to carry out the group No.6 lymphadenectomy. ConclusionsOnly a team shall complete a certain amount of the operation, take the medium vessels of colon, pancreas, and the gastroduodenal artery as the anatomic landmark, accurately identify the space between the anterior lobe and the posterior lobe of transverse mesocolon, and the prepancreatic space, and take operation on the correct surgical plane, shall the group No.6 lymphadenectomy conform to the principle of the radical cure of the tumour and achieve the aim of the minimal invasion.
Objective To explore the operative managements of ectopic gallbladder during laparoscopic cholecystectomy (LC).Methods Twenty one cases of ectopic gallbladder undergone LC in this hospital were analyzed regarding the perioperative management, principle, and technique of operation.Results There were 2 cases of situs transversus, 1 case with gallbladder under right posterior lobe of liver, 2 under left lateral lobe of liver and 16 in the liver. All 21 cases of ectopic gallbladder had undergone LC successfully, and no complications were found during and after operation. Conclusion Anatomic ectopia of gallbladder tosses a challenging problem to laparoscopic surgeon. It is safe for surgeons to recognise actual anatomical anomaly and to manage them appropriately.
The article reports 300 cases of laparoscopic cholecystectomy performed in Chengdu General Hospital of P.L.A. from October 1992 to August 1993. 16 of 300 were converted to open procedure. The number of postoperative complication cases was 12(4%).
Objective To systematically evaluate the efficiency of laparoscopic hepatectomy（LH） and conventionalopen hepatectomy （OH）in patients with hepatocellular carcinoma （HCC）. Methods The literatures about the therap-eutic effect of LH and OH on hepatocellular carcinoma were collected from PubMed， Chinese Journal Full-text Database （CJFD）， Wanfang Database， China Doctor/Master Dissertations Full-text Database （CDMD）， and China Proceedings of Conference Full-text Database （CPCD）from 2000 to 2011. RevMan 5.0 software was used for data analysis. Results Eleven controlled clinical trials were included in this analysis. These studies included a total of 781 patients：325 treated with LH and 456 treated with OH. The results of meta-analysis showed that LH group had shorter operation time〔WMD=-20.85， 95% CI （-29.54， -12.16）， P＜0.000 01〕， less operative blood loss 〔SMD=-0.42，95% CI（-0.65，-0.19）， P=0.000 4〕， a lower postoperative morbidity rate 〔OR=0.43，95% CI （0.28，0.65），P＜0.000 1〕， and shorter hospitalization days 〔WMD=-4.32，95％ CI （-6.29，-2.34），P＜0.000 1〕 than OH group. There was no significant difference in postoperative recurrence （P=0.80）， overall survival in 1-year （P=0.98）， 3-year （P=0.41）， and 5-year （P=0.12）， and in disease-free survival in 1-year （P=0.15）， 3-year （P=0.62）， and 5-year （P=0.99）between the two groups. Conclusions For the patients with hepatocellular carcinoma localized to the CouinaudⅡ，Ⅲ，Ⅳ，Ⅴ，and Ⅵ segments with a maximum lesion size of 5cm， as well as the tumor has no effect on the exposure of blood vessel of the first and second hepatic portal， and the liver functions are classified as Child B or A high grade， the laparoscopic liver resection is priority considered in the conditions allow.
ObjectiveTo evaluate the value of incision closure device in laparoscopic cholecystolithotomy. MethodsThe clinical data of 130 patients underwent laparoscopic cholecystectomy from Oct. 2014 to Feb. 2015 were retrospectively analyzed. According to the methods of gallbladder suture, 130 cases were divided into two groups, 72 cases underwent traditional manual suture (MS group), and 58 cases underwent incision closure device (ICD group). The operative time, postoperative gastrointestinal function recovery time, bleeding volume, postoperative hospitalization time, hospitalization expenses, complications, and postoperative 6-12 months follow-up of patients in 2 groups were observed.Results One hundred and thirty cases were performed laparoscopic cholecystolithotomy successfully. The operative time and postoperative gastrointestinal function recovery time of ICD group were significantly shorter than those of MS group, the difference was statistically significant (P < 0.05). The hospitalization expenses of the patients in ICD group were significantly higher than those in the MD group (P < 0.05). There were no significant difference between the two groups in the bleeding volume and postoperative hospital stay (P > 0.05). The patients were followed up for 6-12 months, with an average of 8 months, and no complications occurred and stone recurrence. ConclusionIncision closure device can shorten the time of laparoscopic cholecystolithotomy and postoperative recovery of gastrointestinal function, but the cost is higher. Next development, still need decrease the expend and strengthen clinical promotion.
